Do neutrinos hold the key to the antimatter-matter conundrum?

One of the big unsolved mysteries in physics is what happened to all the antimatter after the Big Bang. The answer may lie in neutrinos, and at this exhibit you’ll discover why this invisible particle is so very important.

Antimatter is made of particles which have charges opposite of normal matter. At the origin of the universe, matter and antimatter should have been created in equal amounts. So why is almost everything now only made of matter? A tantalizing body of evidence is building to suggest that the invisible elementary particle, the neutrino, may play a key role in tipping the antimatter-matter balance. The teams at Durham University, Queen Mary University of London and the Hyper-Kamiokande UK collaboration are involved in the race to understand these ghostly particles, trillions of which pass unnoticed through our bodies every second. The team aim to understand the differences between neutrinos and antineutrinos, by creating beams of the particles and using giant detectors to study how they change after travelling kilometres from their source.
